Target Limited Editions business jumper, 'silk, cotton, cashmere blend' according to the tag. Tag says $59 but display says $7 as shown in pic, and scans at $7.
Not sure if all stores or online, but appears to be part of an Xmas sale so may be.
Even the sales person was impressed with the price.
I've bought a few shirts with that Limited Editions label on them from Target and I have to say I was impressed by them.
Much better than I had come to expect from Target tbh.
